Hi,
Ive tested this SDL simple example and it doesnt run in my gpu neither.... although it initializes the video mode with SDL_OPENGL
example from http://lazyfoo.net/SDL_tutorials/lesson36/index.php
This is driving me nuts.............
I'll post my glut+Opengl window creation & initialization code soon, now i have to leave.
